[0001] This invention is a divisional application of the applicant's patent application filed on October 25, 2024, with application number 202411505611.1 and titled "Tumor Electric Field Therapy System, Tumor Therapy Equipment, and Electrode Quality Inspection Method". Technical Field

[0002] This application relates to tumor electric field therapy technology, and more particularly to a tumor electric field therapy system and an electrode temperature detection method. Background Art

[0003] Currently, tumor electric field therapy systems mainly include an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode sheets electrically connected to the electric field generator via the adapter. The electric field generator transmits an alternating electric signal for tumor electric field therapy to each electrode sheet via the adapter, and then applies an alternating electric field to the patient's tumor site for tumor electric field therapy through the electrode sheets. Since the alternating electric field applied to the patient will accumulate heat at the corresponding location where the electrode sheet is attached to the skin, in order to avoid low-temperature burns to the skin, a temperature sensor needs to be configured at each electrode unit to monitor the skin surface temperature at each electrode unit. However, during tumor treatment using electrode pads, it is inevitable that a small number of electrode pads will experience malfunctions of individual temperature sensors after a period of use. If too many temperature sensors on an electrode pad malfunction, it can easily lead to the risk of low-temperature burns for the patient.

[0004] This application aims to at least partially solve one of the technical problems in the related art. Therefore, the first objective of this application is to propose a tumor electric field therapy system that can use fewer conductive traces to achieve zoned control of multiple electrode units and sampling of temperature detection signals. This not only improves the effect of tumor electric field therapy but also facilitates electrode pad application. Furthermore, during the use of the electrode pads, the sampled temperature detection signals can be used to monitor whether the electrode pads are damaged, allowing for timely replacement and avoiding or reducing the risk of low-temperature burns for the patient. During the production process of the electrode pads, the sampled temperature detection signals can be used to monitor whether each temperature detection unit of the electrode pad is properly connected, thereby determining whether the electrode pad is qualified and screening out unqualified electrode pads, thus ensuring that each temperature detection unit of the electrode pads leaving the factory can perform normal detection. In addition, the adapter in this embodiment can be adapted to electrode pads with different numbers of electrode units.

The controller is configured to combine the conduction states of each of the grounding wires and each of the dual-purpose signal lines so that (1) when the dual-purpose signal lines conduct DC signal transmission paths to transmit DC signals to the signal terminals of each of the temperature detection units, each of the grounding wires is sequentially and individually conducted so that the temperature detection signals detected by each of the temperature detection units are sampled line by line, and the sampled temperature detection signals detected by each of the temperature detection units are used to determine the test code array of the electrode sheet, and the test code array is used to perform a consistency comparison with the standard code array; (2) when the dual-purpose signal lines conduct AC signal transmission paths, AC signals are transmitted to each of the electrode units.

[0006] A second objective of this application is to provide an electrode sheet quality detection method.

[0007] To achieve the above objectives, a second aspect of this application provides an electrode temperature detection method applied to the aforementioned tumor electric field therapy system. The method includes: switching each of the dual-purpose signal lines to conduct their DC signal transmission paths to provide DC signals to the signal terminals of each of the temperature detection units; sequentially connecting each of the grounding lines to collect the temperature detection signals detected by each temperature detection unit row by row.

Detailed Embodiments

[0026] The embodiments of the technical solutions of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore only examples, and cannot be used to limit the scope of protection of this application.

[0027] Some embodiments:

[0028] FIG1 is a schematic diagram of a tumor electric field therapy system 100 according to a first embodiment of the present application. As shown in FIG1, the tumor electric field therapy system 100 includes: at least one pair of electrode pads 110, an adapter 120 connected to the at least one pair of electrode pads 110, and an electric field generator 130 connected to the adapter 120. The at least one pair of electrode pads 110 can be arranged in pairs on the patient's body surface, as shown in FIG1 with four electrode pads 110, each pair of electrode pads 110 being arranged on the patient's body surface. The electric field generator 130 is used to supply power to the at least one pair of electrode pads 110, such that an alternating electric field for treating tumors is generated between the at least one pair of electrode pads 110. The adapter 120 is electrically connected between the at least one pair of electrode pads 110 and the electric field generator 130, for transmitting the alternating electrical signal generated by the electric field generator 130 to the at least one pair of electrode pads 110. That is, the electric field generator 130 can generate an alternating electric signal, which is transmitted to each electrode 110 through the adapter 120, so that an alternating electric field for tumor treatment is generated between the same pair of electrode 110, so as to apply the alternating electric field to the tumor site of the patient for tumor treatment.

[0029] As shown in FIG1, in this embodiment, there are 4 electrode 110s, and each electrode 110 includes a plurality of electrode units 112 with the same number as described on page 3 / 27 of the specification 6 CN 121371478 A. Each electrode unit 112 is electrically connected to the adapter 120, and there are 20 electrode units 112 on each electrode 110. In other embodiments, the tumor electric field therapy system 100 may have more or fewer electrode pads 110; in other embodiments, each pair of electrode pads 110 has the same number of electrode units 112, and different pairs of electrode pads 110 may have different numbers of electrode units 112; in other embodiments, the number of electrode units 112 on each electrode pad 110 may be 9, 13, 19, etc.

[0030] Figure 2 is a schematic diagram of the circuit connection between an electrode 110 and an adapter 120 of the tumor electric field therapy system 100 shown in Figure 1. It is worth noting that the arrangement of the electrode units 112 shown in Figure 2 is for clearer illustration of the electrical connection between an electrode 110 and the adapter 120; the arrangement of the electrode units 112 shown in Figure 2 does not represent the spatial arrangement of the electrode units 112. Referring to Figures 1 and 2, the electrode 110 includes: a substrate 111, multiple electrode units 112 electrically connected to the substrate 111 at intervals, multiple temperature detection units 113, and a first cable 116 electrically connected to the substrate 111. The substrate 111 may be a flexible circuit board. Multiple conductive traces are embedded in the substrate 111, including multiple ground lines 118 and multiple dual-purpose signal lines 119. The first cable 116 has nine core wires (not shown), each of which is electrically connected to the multiple grounding wires 118 and the multiple dual-purpose signal lines 119 of the substrate 111. In this embodiment, the total number of grounding wires 118 and dual-purpose signal lines 119 embedded in the substrate 111 does not exceed nine, so the number of wires in the first cable 116 does not exceed nine.

[0031] Multiple electrode units 112 are configured into multiple row groups and multiple column groups. In this embodiment, each electrode sheet 110 has 20 electrode units 112, which are arranged in the order of 1 to 20 in the circuit connection and divided into four row groups and five column groups, that is, the 20 electrode units 112 are arranged in four rows and five columns in the circuit connection. Each electrode unit 112 corresponds to a temperature detection unit 113, and each temperature detection unit 113 has a signal terminal 113B and a ground terminal 113A. Both electrode unit 112 and temperature detection unit 113 are soldered onto substrate 111, and the signal terminal 113B of electrode unit 112 and the corresponding temperature detection unit 113 are short-circuited. Since multiple temperature detection units 113 are configured one-to-one with multiple electrode units 112, the multiple temperature detection units 113 are also arranged in a four-row, five-column configuration in their circuit connections. It should be noted that this arrangement is for clearer illustration of the electrical connection between electrode sheet 110 and adapter 120, and does not represent the spatial arrangement of electrode units 112. The spatial structure may be a roughly array-like structure as shown in Figure 1, or other structures such as petal-shaped or scattering structures; it can be regular or irregular. Electrode unit 112 is configured to apply an alternating electrical signal to the patient's tumor site. Temperature detection unit 113 is configured to detect the temperature of the patient's body surface where the electrode sheet 110 is attached, i.e., the temperature at the corresponding electrode unit 112, and output a temperature detection signal to an external device such as adapter 120. In this embodiment, the multi-purpose signal lines 119 of the substrate 111 are respectively connected to the electrode units.Multiple columns of 112 are configured to transmit alternating electrical signals generated by the electric field generator 130 to each electrode unit 112 in the corresponding column. That is, electrode units 112 in the same column are shorted together by the same dual-purpose signal line 119 of the substrate 111, and electrode units 112 in different columns are connected in parallel by different dual-purpose signal lines 119 of the substrate 111. The dual-purpose signal line 119 of the substrate 111 is electrically connected to the first cable 116, and then electrically connected to the electric field generator 130 via the adapter 120. Further, the dual-purpose signal line 119 of the substrate 111 receives the alternating electrical signals generated by the electric field generator 130 through the first cable 116 and the adapter 120.

[0032] Multiple grounding lines 118 are configured to correspond one-to-one with multiple rows of electrode units 112, and the multiple grounding lines 118 are used to short-circuit and ground each temperature detection unit 113 in each row in sequence. That is, the grounding terminals 113A of multiple temperature detection units 113 located in the same row group are all short-circuited through the same grounding line 118 of the substrate 111, and the grounding terminals 113A of temperature detection units 113 located in different row groups are connected in parallel through different grounding lines 118 of the substrate 111. During the temperature detection period, only one of the multiple grounding lines 118 is conducting at any given time, and the rest are disconnected.

[0033] Each of the multiple dual-purpose signal lines 119 is also configured to short-circuit the signal terminal 113B of at most one temperature detection unit 113 in each row group to an external device for receiving detection signals. The signal terminals 113B of the temperature detection units 113 connected to each of the multiple dual-purpose signal lines 119 are different to avoid the dual-purpose signal lines 119 outputting duplicate signals in the future. That is, when the number of electrode units 112 in a row group is the same as the number of dual-purpose signal lines 119, each dual-purpose signal line 119 is electrically connected to the signal terminal 113B of a different temperature detection unit 113 in that row group; when the number of electrode units 112 in a row group is less than the number of dual-purpose signal lines 119, at least one dual-purpose signal line 119 is not electrically connected to the signal terminal 113B of the temperature detection unit 113, and the remaining dual-purpose signal lines 119 are electrically connected to the signal terminal 113B of a different temperature detection unit 113 in that row group. In this embodiment, the external device for receiving the detection signal is an adapter 120. The signal terminals 113B of multiple temperature detection units 113 located in different column groups are connected in parallel through different dual-purpose signal lines 119 of the substrate 111, and the signal terminals 113B of multiple temperature detection units 113 located in the same column group are all short-circuited to the same dual-purpose signal line 119 of the substrate 111.

[0034] In this embodiment, with a temperature detection unit 113 configured in each electrode unit 112 for temperature detection, the above-described circuit design reduces the number of wires in the first cable 116, preventing the cable from becoming thicker and harder, thus increasing the difficulty of cable fixation; simultaneously, it avoids the increased number of wires in the first cable 116 affecting the adhesion between the electrode pad 110 and the corresponding body surface of the patient's tumor site. The substrate 111 has a total of 9 embedded grounding wires 118 and dual-purpose signal lines 119. Specifically, in this embodiment, the substrate 111 has 4 embedded grounding wires 118 and 5 embedded dual-purpose signal lines 119. The number of grounding wires 118 is related to the number of rows M of the electrode unit 112, and is greater than or equal to the number of rows M, where M is a positive integer. The number of dual-purpose signal lines 119 is related to the number of columns N of the electrode unit 112, and is greater than or equal to the number of columns N, where N is a positive integer. The number of lines L embedded in the substrate 111 of the electrode sheet 110 is equal to the sum of the number of grounding lines 118 and the number of dual-purpose signal lines 119. In this embodiment, the number of grounding lines 118 is equal to the number of rows M of the electrode unit 112; the number of dual-purpose signal lines 119 is equal to the number of columns N of the electrode unit 112.

[0035] In terms of spatial structure, multiple electrode units 112 are arranged at intervals on the substrate 111 in a roughly two-dimensional array. As shown in Figure 1, the electrode sheet 110 in this embodiment includes 20 electrode units 112 and 20 temperature detection units 113 corresponding to the electrode units 112. The 20 electrode units 112 are arranged in an array of four rows and six columns. Each of the first and fourth rows has four electrode units 112, and each of the second and third rows has six electrode units 112. The four electrode units 112 in each of the first and fourth rows are located in the second to fifth columns, respectively, and the six electrode units 112 in each of the second and third rows are located in the first to sixth columns, respectively.

[0036] As shown in FIG1, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetrical connection manner. For example, adjacent electrode units 112 in the four electrode units 112 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column are connected by a column-directed connecting strip (unlabeled). At the same time, adjacent electrode units 112 in the four electrode units 112 located in the first row and fifth column, the second row and fifth column, the third row and fifth column, and the fourth row and fifth column are also connected by a column-directed connecting strip (unlabeled). Each electrode sheet 110 has a free end. For example, at least one electrode unit 112 in the multiple electrode units 112 is connected to at most one other electrode unit 112. For example, the electrode units 112 located in the first row and second column, the second row and first column, the second row and second column, the third row and first column, the third row and second column, and the fourth row and second column are connected by a column-directed connecting strip (unlabeled).Each electrode unit 112 is not connected by a connecting strip in its column direction, thus forming an open space. This open space is adjustable. For example, the position of the electrode unit 112 in the first row and second column can be moved relative to the position of the electrode unit 112 in the first row and third column; the position of the electrode unit 112 in the second row and first column can be moved relative to the position of the electrode unit 112 in the second row and second column; the position of the electrode unit 112 in the third row and first column can be moved relative to the position of the electrode unit 112 in the third row and second column; and the position of the electrode unit 112 in the fourth row and second column can be moved relative to the position of the electrode unit 112 in the fourth row and third column. Thus, when the electrode pad 110 is applied to the patient's body surface, the positions of the electrodes in the first row and second column, the second row and first column, the third row and first column, and the fourth row and second column can be adjusted. (Instruction manual page 5 / 27, page 8, CN 121371478 A) The position of electrode unit 112 can be adjusted to create open space between the corresponding electrode units 112, thereby increasing the heat dissipation space of the corresponding electrode units 112 and accelerating heat dissipation. This also allows the patient to adjust the position of the electrode units 112 based on the fever level or the skin condition of the area where the electrode pad 110 is applied. Similarly, the electrode units 112 located in the first row, fourth column, second row, fourth column, second row, sixth column, third row, and fourth row, fourth column, are not connected by connecting bands in the column direction, thus forming open space. This open space is adjustable; for example, the position of electrode unit 112 in the first row, fourth column can be moved relative to the position of electrode unit 112 in the first row, fifth column; the position of electrode unit 112 in the second row, fourth column, and second row, sixth column can be moved relative to the position of electrode unit 112 in the second row, fifth column; the position of electrode unit 112 in the third row, sixth column can be moved relative to the position of electrode unit 112 in the third row, fifth column; and the position of electrode unit 112 in the fourth row, fourth column can be moved relative to the position of electrode unit 112 in the fourth row, fifth column. The positions are movable, so that when the electrode pad 110 is applied to the patient's body surface, the open space between the corresponding electrode units 112 can be adjusted by adjusting the positions of the first row, fourth column, second row, fourth column, second row, sixth column, third row, sixth column, and fourth row, fourth column. This can increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. At the same time, it is beneficial for the patient to adjust the position of the electrode units 112 based on the fever or the skin condition of the area where the electrode pad 110 is applied.

[0037] As shown in Figure 1, in terms of spatial structure, the four electrode units 112 located in the first row can be divided into region 1, the four electrode units 112 located in the second row, first column, third row, second column, and fourth row, third column can be divided into region 2, the four electrode units 112 located in the second row, sixth column, third row, fourth column, and fourth row, fifth column can be divided into region 3, and the four electrode units 112 located in the second row, second row, third column, third row, sixth column, fourth row, and fourth row, fifth column can be divided into region 3.The four electrode units 112 are divided into region 4, and the four electrode units 112 located in the second row and fourth column, the second row and fifth column, the third row and fourth column, and the third row and fifth column are divided into region 5. The electrode units 112 in each region (1-5) correspond to a column group in the circuit connection shown in FIG2, and the corresponding 20 electrode units 112 are arranged in a four-row group and a five-column group in the circuit connection. In some other embodiments, the 20 electrode units 112 can also be arranged in other ways. Of course, in some other embodiments, the electrode sheet 110 can also have other numbers of electrode units 112. In summary, the implementation of this application is not limited by the number and arrangement of the electrode units 112 of the electrode sheet 110.

[0038] Each electrode unit 112 can be applied with an alternating electrical signal, and then the paired electrode sheets 110 are used to apply an alternating electric field to the tumor site of the patient. Optionally, the electrode unit 112 is a dielectric element, such as a ceramic sheet, or a polymer dielectric layer made of polymer material. Each temperature detection unit 113 is provided corresponding to one electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be located at any position of the corresponding electrode unit 112. In this embodiment, each electrode unit 112 is provided with a through hole 1121, which is suitable for installing the temperature detection unit 113. For example, each electrode unit 112 has a through hole 1121 in the middle, and each electrode unit 112 has a corresponding temperature detection unit 113 housed in the through hole 1121. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115. The temperature sensor 114 has a signal terminal 114B and a ground terminal 114A. The diode 115 has an anode 115B and a cathode 115A. The anode 115B of the diode 115 is connected to the ground terminal 114A of the temperature sensor 114, and the cathode 115A of the diode 115 serves as the ground terminal 113A of the temperature detection unit 113. The signal terminal 114B of the temperature sensor 114 serves as the signal terminal 113B of the temperature detection unit 113. The temperature sensor 114 can be a thermistor or other temperature sensor. Each temperature sensor 114 is correspondingly provided with a diode 115. The diode 115 is connected in series with the temperature sensor 114 of the corresponding electrode unit 112. It can prevent the reverse flow of current to prevent the detection signal from other electrode units 112 from affecting the temperature sensor 114.

[0039] As shown in FIG. 2, the electrode sheet 110 of this embodiment includes four grounding wires 118, each grounding wire 118 being used to ground the grounding terminal 113A of the temperature detection unit 113 in the same row group. The four grounding wires 118 of the electrode sheet 110 are respectively the first grounding wire 118, the second grounding wire 118, the third grounding wire 118, the fourth grounding wire 118, the fifth grounding wire 118, the sixth grounding wire 118, the seventh grounding wire 118, the eighth grounding wire 118, the ninth ...Ground wire 118-1, second ground wire 118-2, third ground wire 118-3, and fourth ground wire 118-4. In the four rows of electrode sheet 110, the first row includes electrode units 112-1 to 112-5, the second row includes electrode units 112-6 to 112-10, the third row includes electrode units 112-11 to 112-15, and the fourth row includes electrode units 112-16 to 112-20. Specifically, the first grounding wire 118-1 is used to ground electrode units 112-1 to 112-5 in the first row group; the second grounding wire 118-2 is used to ground electrode units 112-6 to 112-10 in the second row group; the third grounding wire 118-3 is used to ground electrode units 112-11 to 112-15 in the third row group; and the fourth grounding wire 118-4 is used to ground electrode units 112-16 to 112-20 in the fourth row group. It should be noted that these grounding wires 118 can be selectively closed or opened. This can be achieved by connecting each grounding wire 118 in series with a control switch 124. That is, the grounding terminals 113A of the temperature detection units 113 corresponding to each electrode unit 112 in each row group are connected to the grounding pin through a single control switch 124, which will be described in detail below. The aforementioned "grounding the electrode unit 112" can refer to grounding the grounding terminal 114A of the temperature sensor 114 corresponding to each electrode unit 112, or it can refer to the diode 115 being connected in series with the temperature sensor 114 corresponding to the same electrode unit 112 and grounded together. In short, each grounding line 118 short-circuits and grounds the grounding terminals 113A of the temperature detection units 113 corresponding to all electrode units 112 in each row group.

[0040] As shown in FIG2, the electrode sheet 110 of this embodiment also includes 5 dual-purpose signal lines 119. One end of each dual-purpose signal line 119 is connected to all electrode units 112 in each column group, and the other end is connected to the adapter 120 for receiving temperature detection signals and transmitting alternating electrical signals. That is, for each row group, each dual-purpose signal line 119 can be selectively connected to one of the electrode units 112 or not connected to any electrode unit 112 in the row group to avoid the dual-purpose signal line 119 outputting repeated signals in the future. Specifically, the five dual-purpose signal lines 119 of the electrode sheet 110 include a first dual-purpose signal line 119-1, a second dual-purpose signal line 119-2, a third dual-purpose signal line 119-3, a fourth dual-purpose signal line 119-4, and a fifth dual-purpose signal line 119-5. One end of the first dual-purpose signal line 119-1 is simultaneously connected to the signals of four electrode units 112 (electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16) and their corresponding temperature detection units 113.Terminal 113B; one end of the second dual-purpose signal line 119-2 is simultaneously connected to the signal terminal 113B of four electrode units 112 (electrode units 112-2, 112-7, 112-12, and 112-17) and their respective temperature detection units 113; one end of the third dual-purpose signal line 119-3 is simultaneously connected to the signal terminal 113B of four electrode units 112 (electrode units 112-3, 112-8, 112-13, and 112-18) and their respective temperature detection units 113. 3B; One end of the fourth dual-purpose signal line 119-4 is simultaneously connected to the signal terminals 113B of four electrode units 112 (electrode units 112-4, 112-9, 112-14, and 112-19) and their respective temperature detection units 113; One end of the fifth dual-purpose signal line 119-5 is connected to the signal terminals 113B of four electrode units 112 (electrode units 112-5, 112-10, 112-15, and 112-20) and their respective temperature detection units 113. In short, each dual-purpose signal line 119 short-circuits the signal terminals 113B of each electrode unit 112 and its corresponding temperature detection unit 113 in parallel within the same column group as temperature sampling points (unlabeled) for connection to external devices. It should be noted that these dual-purpose signal lines 119 can selectively transmit alternating electrical signals or receive temperature detection signals. This can be achieved by connecting each dual-purpose signal line 119 in series with a bidirectional switching switch 125 and coordinating the closing or opening of the grounding wire 118. In other words, after the signal terminal 113B of each temperature detection unit 113 in each row group is shorted to the corresponding electrode unit 112, they are connected together to a switching unit (unlabeled) via a single dual-purpose signal line 119. This switching unit (unlabeled) includes multiple bidirectional switching switches 125, configured to switch the dual-purpose signal line 119 to either the temperature sampling point (unlabeled) or the alternating power line 127. This allows the switching state of the control switch 124 to adjust the temperature detection of the corresponding temperature detection unit 113 in each row group when the dual-purpose signal line 119 is connected to the temperature sampling point (unlabeled). (Instruction manual 7 / 27 page 10 CN 121371478 A) The signal is sampled based on temperature sampling points (unlabeled), and with the dual-purpose signal line 119 connected to the alternating power line 127, at least one column of electrode units 112 is subjected to an alternating electrical signal based on the alternating power line 127. The analog temperature signal detected by each sampled temperature detection unit 113 is used to determine the test code array of the corresponding electrode piece 110. Each temperature detection unit in the corresponding electrode piece 110 is identified by comparing the test code array with a standard code array.The fault condition of element 113, or the determination of whether the corresponding electrode 110 is qualified, will be described in detail below.

[0041] The multi-path grounding line 118 and the multi-path dual-purpose signal line 119 are both conductive traces embedded in the substrate 111. The substrate 111 is electrically connected to the first cable 116. The multi-path grounding line 118 and the multi-path dual-purpose signal line 119 embedded in the substrate 111 are respectively electrically connected to the corresponding wires (not shown) in the first cable 116.

[0042] The tumor electric field therapy system 100 of this embodiment includes at least one pair of the above-mentioned electrode 110, an adapter 120 electrically connected to the electrode 110, and an electric field generator 130 electrically connected to the adapter 120. The adapter 120 is connected between the electrode 110 and the electric field generator 130. The electric field generator 130 provides alternating electrical signals to multiple electrode units 112 of the electrode sheet 110 via the adapter 120 and the dual-purpose signal line 119 of the electrode sheet 110, or receives temperature detection signals output by the temperature detection units 113 corresponding to the multiple electrode units 112. The adapter 120 transmits the alternating electrical signals generated by the electric field generator 130 to the dual-purpose signal line 119 of the electrode sheet 110, and is also configured to receive temperature detection signals output by the multiple dual-purpose signal lines 119 of the electrode sheet 110.

[0043] Referring to Figures 2 and 3, the adapter 120 includes: a first controller 121, multiple ADC units 122 connected to the first controller 121, multiple voltage-reducing resistors 123 and multiple control switches 124 corresponding to the multiple ADC units 122, multiple bidirectional switching switches 125 corresponding to the multiple ADC units 122, a first communication unit 126, an alternating power line 127 corresponding to each bidirectional switching switch 125, and a first power module 128 connected to the first communication unit 126, the first controller 121, and the multiple ADC units 122. The first power module 128 provides DC power VCC to each electronic component of the adapter 120. The adapter 120 also includes multiple circuit lines (unlabeled), which are electrically connected to the multiple ground lines 118 and multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode 110 via the first cable 116 of the respective electrode 110. The multiple circuit lines (unlabeled) include an alternating power supply line 127 that transmits alternating electrical signals to the corresponding electrode 110 and is electrically connected to the multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode 110; multiple circuit lines (unlabeled) that are electrically connected to the multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode 110 and are used to power the temperature detection units 113 of the electrode 110 or transmit the temperature detection signals of the electrode 110; and multiple circuit lines that are electrically connected to the multiple ground lines 118 in the substrate 111 of the corresponding electrode 110.The connected circuit lines (unlabeled). The number L of circuit lines electrically connected to one electrode piece 110 by the adapter 120 is greater than or equal to the sum of the number of rows and columns of the electrode units 112 of the electrode piece 110; the number H of circuit lines electrically connected to X electrode pieces 110 by the adapter 120 is greater than or equal to X times the number of circuit lines electrically connected to a single electrode piece 110, that is, H=XL≥X×(M+N). In this embodiment, the number L of circuit lines electrically connected to one electrode piece 110 by the adapter 120 is equal to the sum of the number of rows and columns of the electrode units 112 of the electrode piece 110; the number H of circuit lines electrically connected to X electrode pieces 110 by the adapter 120 is equal to X times the number of circuit lines electrically connected to a single electrode piece 110, that is, H=XL=X×(M+N). The number of groups of control switches 124 and the number of groups of bidirectional switching switches 125 are both related to the number of electrode pieces 110. The number of control switches 124 is the same as the number of bidirectional switching switches 125, and is not less than the number of electrode plates 110. Optionally, the number of control switches 124 and bidirectional switching switches 125 is the same as the number of electrode plates 110. The following is a detailed description of the electrical connection between an electrode plate 110 with 20 electrode units 112 and the adapter 120.

[0044] Each group of control switches 124 is provided with multiple control switches 124. The multiple control switches 124 are respectively connected to the adapter 120 and electrically connected to the circuit lines (unnumbered) corresponding to the multiple grounding wires 118 of a corresponding electrode plate 110, and are configured to control the conduction or disconnection of the multiple grounding wires 118. The circuit lines (unnumbered) of the multiple grounding wires 118 of the electrode plate 110 are grounded to GND at the end near the control switch 124. The number of control switches 124 in each group of control switches 124 is related to the number of grounding wires 118 on the substrate 111 of the corresponding electrode sheet 110; in this embodiment, the two are equal. As shown in Figure 2, in this embodiment, the multiple control switches 124 in each group of control switches 124 are respectively the first control switch 124-1, the second control switch 124-2, the third control switch 124-3, and the fourth control switch 124-4. The multiple control switches 124 in the same group each control the closing or opening of the corresponding grounding wire 118 of the same electrode sheet 110. Specifically, the first control switch 124-1 is used to control the opening or closing of the first grounding wire 118-1 of the corresponding electrode plate 110, and can then cooperate with the corresponding set of bidirectional switching switches 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 from electrode unit 112-1 to electrode unit 112-5 in the first row of the electrode plate 110; the second control switch 124-2 is used to control the opening or closing of the second grounding wire 118-2 of the electrode plate 110, and can then cooperate with the corresponding set of bidirectional switching switches 125.The first control switch 124-3 controls the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 (112-6 to 112-10) in the second row of the electrode plate 110. The second control switch 124-3 controls the opening and closing of the third grounding wire 118-3 of the electrode plate 110, and can cooperate with the corresponding bidirectional switching switch 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 (112-11 to 112-15) in the third row of the electrode plate 110. The third control switch 124-4 controls the opening and closing of the fourth grounding wire 118-4 of the electrode plate 110, and can cooperate with the corresponding bidirectional switching switch 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 (112-16 to 112-20) in the fourth row of the electrode plate 110. The control switch 124 mentioned above can be a mechanical switch, such as a relay. The control switch 124 can also be an electronic switch, and each control switch 124 can be opened and closed by an additional first controller 121.

[0045] In this embodiment, all of the multiple sets of control switches 124 are electronic switches. The first controller 121 is communicatively connected to the multiple sets of control switches 124 and is used to sequentially and cyclically control the opening and closing states of multiple control switches 124 in each set of control switches 124, thereby sequentially and individually turning on each of the multiple grounding wires 118 of the corresponding electrode pad 110 and cooperating with the switching of the corresponding bidirectional switching switch 125 to collect the temperature of the patient's body surface detected by all temperature detection units 113 on the electrode pad 110. The number of each set of control switches 124 is not less than the number of grounding wires 118 of the substrate 111 of the corresponding electrode pad 110. In this embodiment, the number of each set of control switches 124 is the same as the number of grounding wires 118 of the corresponding electrode pad 110.

[0046] Each group of bidirectional switching switches 125 is provided with multiple bidirectional switching switches 125. The multiple bidirectional switching switches 125 in each group are respectively connected to the adapter 120 and electrically connected to the circuit lines (unlabeled) corresponding to the multi-purpose signal lines 119 of the corresponding electrode plate 110. The number of bidirectional switching switches 125 in each group of bidirectional switching switches 125 is related to the number of dual-purpose signal lines 119 of the substrate 111 of the corresponding electrode plate 110, which is greater than or equal to the number of dual-purpose signal lines 119 of the substrate 111 of the corresponding electrode plate 110. In this embodiment, the two are equal. Each bidirectional switching switch 125 has two ends labeled 1 and 2. The 1 end of the multiple bidirectional switching switches 125 in the same group is electrically connected to the corresponding detection channels in the multiple detection channels of the corresponding group of ADC units 122 through temperature sampling points (unlabeled).Each bidirectional switch 125 has two terminals electrically connected to the corresponding AC power line 127, and is configured to control the multi-channel dual-purpose signal line 119 to connect to the corresponding AC power line 127 to transmit AC electrical signals or to connect to the corresponding detection channel of the corresponding group of ADC units 122 to receive the temperature detection signal output by the temperature detection unit 113.

[0047] As shown in FIG2, taking an electrode plate 110 electrically connected to the adapter 120 as an example, in this embodiment with 20 electrode units 112, the multiple bidirectional switches 125 in each group of bidirectional switches 125 are respectively the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4, and the fifth bidirectional switch 125-5. The multiple bidirectional switches 125 in the same group control the switching of a corresponding dual-purpose signal line 119 in the multi-channel dual-purpose signal line 119 of the same electrode plate 110 between transmitting AC electrical signals and transmitting temperature detection signals. In the specification, page 9 / 27, document number 12, CN 121371478 A, specifically, the first bidirectional switching switch 125-1 is used to control the switching of the first dual-purpose signal line 119-1 of the corresponding electrode plate 110 between transmitting alternating electrical signals and transmitting temperature detection signals.

The bidirectional switching switch 125 can be a mechanical switch, such as a relay. The bidirectional switching switch 125 can also be an electronic switch, and each bidirectional switching switch 125 can be switched by an additional first controller 121.

[0048] In this embodiment, all of the bidirectional switching switches 125 are electronic switches. The first controller 121 is communicatively connected to multiple sets of bidirectional switching switches 125, and is used to control the switching of multiple bidirectional switching switches 125 in each set of bidirectional switching switches 125 between their respective terminals 1 and 2, and cooperate with the closing or opening of the corresponding control switch 124 to continuously monitor the temperature of the patient's body surface detected by all temperature detection units 113 on the electrode pad 110 or transmit alternating electrical signals to the patient.

[0049] In this embodiment, each set of ADC units 122 is electrically connected to terminals 1 of multiple bidirectional switching switches 125 in the corresponding set of bidirectional switching switches 125 through multiple circuit lines (unlabeled) in the adapter 120, and is configured to receive the temperature detection signal transmitted by the multi-channel dual-purpose signal line 119 of the corresponding electrode pad 110, and convert the temperature detection signal from analog signal to digital signal. Each ADC unit 122 includes multiple detection channels A, B, C, D, and E, each corresponding to a specific temperature detection point (unlabeled). Each detection channel A, B, C, D, and E is connected via a corresponding bidirectional switch 125.The multi-channel dual-purpose signal line 119 corresponds to one dual-purpose signal line 119. As shown in Figure 2, each ADC unit 122 contains a total of 5 detection channels A, B, C, D, and E, which are respectively the first detection channel A, the second detection channel B, the third detection channel C, the fourth detection channel D, and the fifth detection channel E. The first detection channel A is connected to the first dual-purpose signal line 119-1 through terminal 1 of the first bidirectional switch 125-1; the second detection channel B is connected to the second dual-purpose signal line 119-2 through terminal 1 of the second bidirectional switch 125-2; the third detection channel C is connected to the third dual-purpose signal line 119-3 through terminal 1 of the third bidirectional switch 125-3; the fourth detection channel D is connected to the fourth dual-purpose signal line 119-4 through terminal 1 of the fourth bidirectional switch 125-4; and the fifth detection channel E is connected to the fifth dual-purpose signal line 119-5 through terminal 1 of the fifth bidirectional switch 125-5. Each detection channel A, B, C, D, and E is used to receive the temperature detection signal collected by the temperature detection unit 113 corresponding to the electrode unit 112 connected to the corresponding dual-purpose signal line 119. Additionally, each detection channel A, B, C, D, and E is connected via a corresponding voltage divider resistor 123 within the adapter 120 to a first power module 128 that provides detection voltage to that detection channel A, B, C, D, and E. The first power module 128 provides DC power.

[0050] In this embodiment, the first controller 121 is also configured to determine the test code array of the corresponding electrode piece 110 based on the sampled analog temperature signal detected by each temperature detection unit 113, and to perform a consistency comparison between the test code array and the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode piece 110. The standard code array is the code array when the electrode piece 110 is qualified. The adapter 120 may also include a reminder unit (not shown). When the first controller 121 detects a faulty temperature detection unit 113 in the electrode 110, it controls the reminder unit (not shown) to issue a first reminder message and instructs the electric field generator 130 to continue working. For example, when the first controller 121 detects no faulty temperature detection unit 113 in the electrode 110, it controls the reminder unit (not shown) to light up a green indicator light, while when a faulty temperature detection unit 113 is detected in the electrode 110, it controls the reminder unit (not shown) to light up a red indicator light.

[0051] In this embodiment, the first controller 121 is also configured to determine the number of faulty temperature detection units 113 in the electrode 110 when performing a consistency comparison between the test code array and the standard code array, and to determine whether the electrode 110 needs to be replaced based on the number. For example, when the number exceeds a preset number (which can be set to a minimum of 1), it is determined that the electrode 110 needs to be replaced, while when the number does not exceed the preset number, it is determined that the electrode 110 does not need to be replaced. The first controller 121 may also...When it is determined that the electrode plate 110 needs to be replaced, the control reminder unit (not shown) issues a second reminder message and instructs the electric field generator 130 to stop working. For example, when the first controller 121 determines that the electrode plate 110 needs to be replaced, it controls the reminder unit (not shown) to light up an indicator light red and flash, and at the same time controls the reminder unit (not shown) to sound an alarm such as a buzzer.

[0052] In this embodiment, the first communication unit 126 is configured to acquire digital signals output by multiple ADC units 122 and send the digital signals to the electric field generator 130. The electric field generator 130 is also configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 112 of the electrode plate 110 according to the received digital signal. For example, when any of the received digital signals exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 113 corresponding to at least one electrode unit 112 in the electrode sheet 110 exceeds the preset temperature threshold (e.g., 41°C, 42°C, etc.). In this case, the voltage of the alternating current signal output by the electric field generator 130 can be appropriately reduced to prevent the electrode unit 112 of the electrode sheet 110 from becoming too hot when the alternating current signal is applied, thus avoiding low-temperature burns to the patient's skin. The aforementioned preset temperature threshold and preset threshold can be determined based on human safety thresholds. The first communication unit 126 is controlled by the first controller 121 and serially transmits digital signals converted by multiple sets of ADC units 122. In this embodiment, the preset temperature threshold can be a value within the range of 36°C to 45°C. In this embodiment, the electric field generator 130 is also configured to determine the test code array of the corresponding electrode sheet 110 based on the analog temperature signal detected by each sampled temperature detection unit 113, and to perform a consistency comparison between the test code array and the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110.

The AC signal generator 132 is electrically connected to this group of power supply switches 133 via multiple AC power lines 134. Specifically, the number of power supply switches 133 in the electric field generator 130 is related to the number of electrode 110s; in this embodiment, the number of power supply switches 133 is equal to the number of electrode 110s, and both are four. The power supply switches 133 include a first power supply switch 133-1, a second power supply switch 133-2, a third power supply switch 133-3, and a fourth power supply switch 133-4, each electrically connected to conductors 1 to 4 of the second connector 150 in a one-to-one correspondence. One end of the first power supply switch 133-1 is electrically connected to the AC signal generator 132 via the AC power supply line of the electric field generator 130, and the other end is electrically connected to the corresponding conductor 1 for transmitting alternating electrical signals in the second connector 150 via an AC power supply line 134-1, and then electrically connected to the alternating power supply line 127 located at port X1 of the adapter 120 via the conductor 1 of the second connector 150. The alternating power supply line 127 located at port X1 of the adapter 120 is electrically connected to the first connector 140.The first connector 140 at port X1 of adapter 120 is electrically connected to the corresponding electrode 110 to control whether the AC signal generator 132 supplies an alternating electrical signal to the electrode 110 electrically connected to port X1 of adapter 120; the second power supply switch 133-2 One end of the third power switch 133-3 is electrically connected to the AC signal generator 132 via the AC power line of the electric field generator 130, and the other end is electrically connected to the corresponding alternating signal transmission wire 2 in the second connector 150 via an AC power line 134-2.

The alternating power line 127 at port Y1 of the adapter 120 is electrically connected to the first connector 140. The first connector 140 at port Y1 of the adapter 120 is electrically connected to the corresponding electrode 110, thereby controlling whether the AC signal generator 132 supplies alternating signals to the electrode 110 electrically connected to port Y1 of the adapter 120.

[0056] In this embodiment, the second controller 131 is also configured to determine the test code array of the corresponding electrode plate 110 according to the simulated temperature signal detected by each sampled temperature detection unit 113, and compare the test code array with the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode plate 110. Electric field generator130 may also include a reminder unit (not shown). When the second controller 131 detects a faulty temperature detection unit 113 in the electrode 110, it controls the reminder unit (not shown) to issue a first reminder message and continues to control the AC signal generator 132 to output an alternating electrical signal.

[0059] The working principle of the tumor electric field therapy system 100 of this embodiment will be described in detail below with reference to Figures 2 to 4.

[0060] Specifically, when it is necessary to detect the temperature at each electrode unit 112 of a certain electrode plate 110, the adapter 120...A controller 121 or a second controller 131 of an electric field generator 130 controls each of a set of bidirectional switching switches 125 electrically connected to the electrode 110 to turn on one end and turn off the other end, thereby disconnecting the alternating electrical signal applied to the electrode 110. At the same time, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of a set of control switches 124 electrically connected to the electrode 110 to turn on sequentially in a time-division manner. At this time, the temperature detection signals collected by each temperature detection unit 113 corresponding to each electrode unit 112 in each row of the electrode 110 can be collected sequentially in a time-division manner through multiple detection channels A, B, C, D, and E of a set of ADC units 122 corresponding to the electrode 110. Each detection channel A, B, C, D, and E of each ADC unit 122 simultaneously acquires only the temperature detection signal from the temperature detection unit 113 corresponding to each electrode unit 112 in the same row of the electrode plate 110. The temperature detection signal can be characterized by a voltage value. Of the four control switches 124 corresponding to the electrode plate 110, only one can be on at any given time, while the other three can be off. (See page 14 / 27 of the specification, CN 121371478 A) All five bidirectional switches 125 of a set of bidirectional switches 125 corresponding to the ADC unit 122 are switched to their respective terminals 1, so that each dual-purpose signal line 119 of the electrode 110 is electrically connected to the corresponding detection channels A, B, C, D, and E of the corresponding ADC unit 122 and thus conducts. With this configuration, the ADC unit 122 can collect the voltage values ​​of all temperature detection units 113 corresponding to each electrode unit 112 in the same row group that are shorted by a ground line 118 corresponding to the control switch 124 that is in operation.

[0061] Specifically, when control switch 124-1 is closed, control switches 124-2, 124-3, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-1 to 112-5 in the first row group are energized, and the electrode units 112-6 in the remaining rows are energized. When the temperature detection units 113 corresponding to electrode units 112-20 are de-energized, the signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 in the first detection channel A of the ADC unit 122 are shorted. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-1 is turned on,The grounding terminals 113A of the temperature detection units 113 corresponding to electrode units 112-6, 112-11, and 112-16 are all disconnected. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114. This does not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-1. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-1 is effectively operating on the first detection channel A of this ADC unit 122. The temperature detection signal (voltage value) acquired by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-1. Similarly, the voltage value acquired on the second detection channel B of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-2. The voltage value acquired on the third detection channel C of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-3. The voltage value collected on the fourth detection channel D in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-4. The voltage value collected on the fifth detection channel E in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-5.

[0062] When the control switch 124-2 is closed, and the control switches 124-1, 124-3, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to the electrode units 112-6 to 112-10 in the second row are energized, and the electrode units 112-1 to 112-5 and the electrode units 112-11 to 112-2 in the other rows are energized. When the temperature detection units 113 corresponding to 0 are de-energized, the signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 in the first detection channel A of the ADC unit 122 are shorted. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-6 is grounded, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-11, and 112-16 are open, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, it will not affect the temperature of electrode unit 112-6.The resistance value of detection unit 113 is the same as that of electrode unit 112-6. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-6 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Similarly, the voltage value collected on the second detection channel B of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-7. The voltage value collected on the third detection channel C of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-8. The voltage value collected on the fourth detection channel D of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-9. The voltage value collected on the fifth detection channel E in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode units 112-10.

[0063] When control switch 124-3 is closed, and control switches 124-1, 124-2, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-11 to 112-15 in the third row group are energized, and the temperature detection units 113 corresponding to electrode units 112-1 to 112-10 and electrode units 112-16 to 112-20 in the other rows are de-energized. Electrode units 112-1, 112-6, and 112-11 are short-circuited on the first detection channel A of the ADC unit 122 in this group. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-11 is grounded, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-11 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-11 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage) acquired by the first detection channel A is...The voltage value is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Similarly, the voltage value collected on the second detection channel B in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-12. The voltage value collected on the third detection channel C in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-13. The voltage value collected on the fourth detection channel D in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-14. The voltage value collected on the fifth detection channel E in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-15.

[0064] When control switch 124-4 is closed, control switches 124-1, 124-2 and 124-3 are all open. Furthermore, the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4, and the fifth bidirectional switch 125-5 are all switched to their respective terminals 1. The temperature detection units 113 corresponding to electrode units 112-16 to 112-20 in the fourth row are energized, while the temperature detection units 113 corresponding to electrode units 112-11 to 112-15 in the remaining rows are de-energized. The electrode unit on the first detection channel A of the ADC unit 122 in this group is short-circuited. Since only the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16 is grounded, while the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-1, electrode unit 112-6, and electrode unit 112-11 is disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, it will not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-16. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-16 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Similarly, the voltage value acquired on the second detection channel B in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-17. The voltage value acquired on the third detection channel C in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-18. The fourth...The voltage value collected on detection channel D is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-19. The voltage value collected on the fifth detection channel E in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-20.

[0065] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all electrode units 112 of the electrode piece 110 through a set of bidirectional switching switches 125 and a set of control switches 124, which are electrically connected to a certain electrode piece 110. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be simultaneously connected to the corresponding temperature sampling points (unlabeled), and the switching state of the corresponding control switch 124 is configured so that the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group is sampled based on the corresponding temperature sampling point (unlabeled). Similarly, the temperature detection signals of the temperature detection units 113 of each electrode unit 112 of other electrode sheets 110 can be obtained.

[0066] The first controller 121 or the second controller 131, the multiple ADC units 122, and the multiple bidirectional switching switches 125 can automatically perform operations through pre-programmed program code. For example, the first controller 121 or the second controller 131 first controls all the bidirectional switching switches 125 in the corresponding group to switch to end 1, so that all ends 1 of these bidirectional switching switches 125 are turned on and all ends 2 are turned off, so that each dual-purpose signal line 119 of the corresponding electrode plate 110 is electrically connected to the corresponding group of ADC units 122. Then, the control switch 124-1 in the corresponding group of control switches 124 is closed, and the remaining control switches 124-2 to 124-4 in the group of control switches 124 are turned off. During this period, each detection channel A, B, C, D, and E of the group of ADC units 122 acquires the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 in the first row of the corresponding electrode plate 110, converts it into a digital signal, and stores it in a separately set memory. Then, after a preset time interval, The first controller 121 or the second controller 131 then closes control switch 124-2 in the group of control switches 124, and opens control switches 124-1, 124-3, and 124-4 in the same group of control switches 124. During this period, each detection channel A, B, C, D, and E of the ADC unit 122 in this group acquires the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 located in the second row group. By sequentially and individually turning on each control switch 124 in the group of control switches 124, the temperature can be obtained.Temperature detection signals of all temperature detection units 113 on electrode plate 110. Similarly, temperature detection signals of all temperature detection units 113 on at least one pair of electrode plates 110 are obtained through this operation.

[0067] It should be noted that, in some other embodiments, a set of bidirectional switching switches 125 and a set of control switches electrically connected to a certain electrode plate 110 can be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to realize the acquisition of temperature detection signals of temperature detection units 113 corresponding to some electrode units 112 of the electrode plate 110 during the same temperature acquisition time period. For example, when only the first bidirectional switch 125-1 is switched to its terminal 1, switch 124-1 can be closed first, and switches 124-2, 124-3, and 124-4 can all be opened. At this time, only the temperature detection unit 113 corresponding to the electrode unit 112-1 of the first row group is energized. The signal terminal 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 in the first detection channel A of the ADC unit 122 of this group is shorted. Therefore, the ADC unit 122 of this group... The voltage value of the temperature detection unit 113 corresponding to electrode unit 112-1 will be detected. Then, control switch 124-2 will be closed, and control switches 124-1, 124-3, and 124-4 will all be opened. At this time, the ADC unit 122 will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Then, control switch 124-3 will be closed, and control switches 124-1, 124-2, and 124-4 will all be opened. At this time, the ADC unit 122 will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Finally, control switch 124-4 will be closed, and control switches 124-1, 124-2, and 124-3 will all be opened. At this time, the ADC unit 122 will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Therefore, within the same acquisition time period, only the temperature detection signal of the temperature detection unit 113 corresponding to one column of electrode units 112 can be sampled. Similarly, the temperature detection signals of the temperature detection units 113 corresponding to other column groups of electrode units 112 can be sampled during other acquisition time periods. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the corresponding temperature sampling point (unlabeled), and the switching state of the control switch 124 is configured so that the temperature detection signals detected by each temperature detection unit 113 in each column group are sampled separately. It should be noted that in some other embodiments, the temperature detection signals of two columns of electrode units 112 can also be sampled within the same acquisition time period.The temperature detection signals of the temperature detection units 113 corresponding to the group, three-row group or four-row group of electrode units 112 are sampled, and the specific details will not be elaborated here.

[0068] Specifically, when it is necessary to apply an alternating electrical signal to each electrode unit 112 of a certain electrode plate 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the multiple bidirectional switching switches 125 of a group of bidirectional switching switches 125 electrically connected to the electrode plate 110 to turn on 2 and turn off 1, and at the same time controls all the multiple control switches 124 of a group of control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to each electrode unit 112 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be simultaneously connected to the alternating power supply line 127, so that the electrode units 112 of at least two column groups are simultaneously subjected to alternating electrical signals based on the alternating power supply line 127.

[0069] It should be noted that, in some other embodiments, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can also control a set of bidirectional switching switches 125 electrically connected to a certain electrode piece 110 to apply alternating electrical signals to some electrode units 112 of the electrode piece 110 in the same time period. For example, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the first bidirectional switch 125-1 of a group of bidirectional switches 125 electrically connected to the electrode plate 110 to turn on at both ends and turn off at the other end. At the same time, it controls all the control switches 124 of a group of control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to the first column of electrode units 112-1, 112-6, 112-11 and 112-16 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the alternating power supply line 127, so that the electrode unit 112 of each column group is simultaneously subjected to an alternating electrical signal based on the alternating power supply line 127. It should be noted that in some other embodiments, two, three, or four column groups can also be switched simultaneously within the same time period.The electrode unit 112 in the array simultaneously applies an alternating electrical signal, the details of which will not be elaborated here.

[0070] Specifically, during the use of the electrode pad 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the test code array of the electrode pad 110 based on the temperature detection signal detected by each temperature detection unit 113, and compare the test code array with the standard code array to monitor whether the electrode pad 110 is damaged, so as to replace the electrode pad 110 in time and avoid or reduce the risk of low-temperature burns to the patient. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, which has the characteristic that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. Since the electrode pad 110 is applied to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a negative temperature coefficient thermistor with a temperature range of 0°C to 50°C can be selected. For example, you can choose a thermistor with model number NCP18XH103D03RB. When the temperature it senses is 0℃, the corresponding resistance is approximately 27.45KΩ; when the temperature it senses is 25℃, the corresponding resistance is approximately 10.0KΩ; and when the temperature it senses is 50℃, the corresponding resistance is approximately 4.16KΩ.

[0071] As shown in Figure 5, when any control switch 124 is turned on, the DC power supply VCC provides DC power to the voltage divider resistor 123, temperature sensor 114 and diode 115 in sequence. The ADC unit 122 in the adapter 120 collects the voltage between the temperature sensor 114 and the voltage divider resistor 123 through the corresponding acquisition channel, that is, the voltage division between the temperature sensor 114 and the diode 115 and the voltage divider resistor 123, and obtains the AD sampling value, i.e. the voltage value (the voltage value of the thermistor), as shown in the following formula (1):

[0072] VADC=(VCC-VD)×R / (Rz+R) (1)

[0073] Wherein, VADC is the AD sampling value, i.e. the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of the diode 115, R is the resistance value of the thermistor, and Rz is the resistance value of the voltage divider resistor 123.

[0074] Assuming the voltage drop VD of diode 115 is 0.3V and the resistance Rz of voltage divider resistor 123 is 10KΩ, then when the temperature sensed by temperature sensor 114 is 0℃, the corresponding resistance is approximately 27.45KΩ. Based on formula (1), the corresponding AD sampling value V0 = (3.3 - 0.3) × 27.45 / (10 + 27.45) = 2.20V can be obtained; when the temperature sensed by temperature sensor 114 is 25℃, the corresponding resistance is approximately 10.0KΩ. Based on formula (1), the corresponding AD sampling value V25 = (3.3 - 0.3) × 10 / (10+10)=1.50V; When the temperature sensed by the temperature sensor 114 is 50℃, the corresponding resistance is about 4.16KΩ. Based on formula (1), the corresponding AD sampling value V50=(3.3-0.3)×4.16 / (10+4.16)=0.88V can be obtained. When the temperature sensor 114 is disconnected, for example, due to abnormal welding of the temperature sensor 114 or open circuit of the temperature sensor 114, the corresponding AD sampling value can be obtained as 3.3V. When the temperature sensor 114 and diode 115 are short-circuited, the corresponding AD sampling value can be obtained as 0V.

[0075] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, the temperature sensor 114 has different voltage values ​​corresponding to different temperatures. Therefore, the voltage value collected by the ADC unit 122 can be reasonably segmented for differentiation. At the same time, the voltage value is converted into the corresponding code. That is, the voltage range in which the voltage value is located corresponds to different codes. Based on the code, the test code array of the electrode sheet 110 can be determined. The test code array includes at least one of a first code, a second code, and a third code. The first code indicates that the temperature detection unit 113 is in a normal state, the second code indicates that the temperature detection unit 113 is in an open-circuit state or an unset state, and the third code indicates that the temperature detection unit 113 is in a short-circuit state.

[0076] Specifically, taking the temperature sensor 114 sensing a temperature in the range of 0℃ to 50℃, and the AD sampling value obtained by the ADC unit 122 sampling in the range of 0.88V to 2.20V as an example, considering factors such as detection error, the range of voltage value can be appropriately expanded to 0.5V to 3V.

[0077] When the AD sampling value obtained by the ADC unit 122 sampling is greater than 0.5V and less than 3V, the corresponding code is the first code, such as 1; when the AD sampling value obtained by the ADC unit 122 sampling is less than or equal to 0.3V, the corresponding code is the third code, such as 0; when the AD sampling value obtained by the ADC unit 122 sampling is greater than or equal to 3.1V, the corresponding code is the second code, such as 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode sheet 110, if the temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if the temperature sensor 114 is present, the corresponding code is 1, i.e., the first code; if the temperature sensor 114 is absent or disconnected, the corresponding code is 2, i.e., the second code.

[0078] Referring to Figure 2, under normal circumstances, when the electrode sheet 110 has 20 electrode units 112, and each electrode unit 112 corresponds to a temperature sensor 114 and a diode 115, that is, the corresponding detection positions numbered 1 to 20 of the electrode sheet 110 all have a temperature sensor 114, and the code is 1. Combining the 20 codes, a 20-bit standard code array 11111 of the electrode sheet 110 is obtained.11111 11111 11111. When temperature sensor 114 experiences an open circuit, assuming the temperature sensor at detection bit 1 is open-circuited, the resulting 20-bit test code array is 21111 11111 11111 11111. When temperature sensor 114 experiences a short circuit, assuming the temperature sensor at detection bit 1 is short-circuited, the resulting 20-bit test code array is 01111 11111 11111 11111.

[0079] Based on the above coding rules, the quality of the electrode pad 110 can be inspected during use so that the electrode pad 110 can be replaced in time to avoid low-temperature burns. The specific process is as follows:

[0080] Step 1: Provide at least one pair of qualified electrode pads 110 (since the electrode pad 110 is a medical device, each electrode pad 110 will undergo multiple tests before leaving the factory to ensure that the electrode pad 110 is qualified. Therefore, the electrode pads 110 provided to the user are all qualified electrode pads 110). Connect at least one pair of qualified electrode pads 110 to the aforementioned adapter 120, and connect the aforementioned adapter 120 to the aforementioned electric field generator 130.

[0081] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection unit in the at least one pair of qualified electrode pads 110 for temperature detection. The ADC unit 122 in the adapter 120 acquires the analog temperature signal detected by the temperature detection unit 113 of at least one pair of qualified electrode pads 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of standard code arrays A1 and A2 according to the aforementioned encoding rules. The at least two sets of standard code arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.

[0082] Step 3: Turn off the power of the electric field generator 130 and place the aforementioned at least one pair of qualified electrode pads 110 on the body surface corresponding to the tumor part of the patient.

[0083] Step 4: Turn on the electric field generator 130 to provide DC power VCC to the temperature detection unit 113 in at least one pair of qualified electrode pads 110 for temperature detection, and at the same time provide an alternating electric signal to the electrode unit 112 in the electrode pads 110 to form an alternating electric field between the paired electrode pads 110 for tumor electric field therapy. The ADC unit 122 in the adapter 120 acquires the temperature signal detected by the temperature detection unit 113 of at least one pair of qualified electrode plates 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of detection code arrays B1' and B2' according to the aforementioned encoding rules.

[0084] Step 5: The first controller 121 in the adapter 120 matches the detection code arrays B1' and B2' with the corresponding standard values.The quasi-encoding arrays A1 and A2 are compared one by one. If the detection encoding arrays B1' and B2' are consistent with the standard encoding arrays A1 and A2, then steps four and five are repeated. If at least one detection encoding array B1' or B2' is inconsistent with the standard encoding arrays A1 and A2, then step six is ​​performed.

[0085] Step six: The adapter 120 confirms the number of abnormal temperature detection units 113 in the electrode plate 110 corresponding to the inconsistent detection encoding arrays B1' and / or B2', and determines whether the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 exceeds the upper limit. If it does not exceed the upper limit, then step seven is performed; if it exceeds the upper limit, then step eight is performed.

[0086] Step seven: Steps four and five are repeated.

[0087] Step 8: The adapter 120 issues an alarm through its internal reminder unit (not shown), and simultaneously sends a corresponding signal to the electric field generator 130 through the first communication unit 126, so that the electric field generator 130 stops providing alternating electrical signals to the electrode unit 112 in the electrode plate 110, reminding the user to replace the corresponding electrode plate 110.

[0088] Step 9: Turn off the power to the electric field generator 130, remove the electrode plate 110 that needs to be replaced from the adapter 120, and connect the new electrode plate 110 to the adapter 120.

[0089] Step 10: Power on the electric field generator 130 to continue providing DC power VCC to the temperature detection unit 113 in the electrode plate 110 connected to the adapter 120 for temperature detection. The ADC unit 122 in the adapter 120 acquires the temperature signal detected by the temperature detection unit 113 of the replaced qualified electrode 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains a new standard code array A1' or / and A2' according to the aforementioned encoding rules. At least one new standard code array A1' or / and A2' is compared with the corresponding standard code array A1 or / and A2 stored above. If the new standard code array A1' or / and A2' is consistent with the standard code array A1 or / and A2, the electric field generator 130 is turned off. The source is to place the new electrode 110, after replacement, on the corresponding body surface of the patient's tumor area, and then repeat steps four and five; if, after comparing the new standard code array A1' and / or A2' with the previously stored standard codes A1 and / or A2 one by one, there is at least one set of new standard code arrays A1' and / or A2' that are inconsistent with the previously stored and corresponding standard code arrays A1 and / or A2, then repeat steps nine and ten until the new standard code arrays A1' and / or A2' of the qualified electrode 110 that are replaced are consistent with the previously stored and corresponding standard code arrays A1 and / or A2.

[0090] It should be noted that, in the above steps, the paired electrode 110s can use electrode 110s of the same design, that is,The standard coding arrays of the corresponding electrode plates 110 are the same, that is, the standard coding arrays A1 and A2 are the same.

[0091] Steps one and two above can be replaced by the user inputting at least two sets of standard coding arrays A1 and A2. At least two sets of standard coding arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes. Specification 20 / 27 pages 23 CN 121371478 A

[0092] In step six above, the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 is determined by the number of codes that differ from the corresponding standard coding arrays A1' and / or A2'. For example, if A1' is compared with A1 and only the first code is different, then the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 is 1; or if A1' is compared with A1 and only the last two codes are different, then the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 is 2; and so on.

[0093] In step six above, the upper limit can be set to 1, that is, if there is an abnormality in one temperature detection unit 113 on the electrode 110, then step eight (alarm and replacement of electrode 110) is performed. In other embodiments, in step six above, the upper limit is not limited to 1, and can also be a positive integer close to the proportion of the number of temperature detection units 113 on the electrode 110.

[0094] In step eight above, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding one-to-one with the electrode 110, indicating the status of the corresponding electrode 110. When the electrode 110 does not need to be replaced, the indicator lights (not shown) are all green; when the electrode 110 needs to be replaced, the indicator light (not shown) of the corresponding electrode 110 that needs to be replaced is red. The status of the electrode 110 not needing to be replaced or needing to be replaced can also be indicated by the indicator lights (not shown) being constantly lit or flashing.

[0095] In step eight above, the reminder unit (not shown) may also include a buzzer (not shown) to indicate the status of the electrode 110, and to remind the user simultaneously with the indicator light (not shown). When the electrode 110 does not need to be replaced, the buzzer (not shown) does not emit an alarm; when the electrode 110 needs to be replaced, the buzzer (not shown) emits an alarm.

[0096] While comparing the detection code array with the standard code array in steps four, five, and six above, temperature monitoring is also performed simultaneously, including the following steps:

[0097] Step eleven: The first controller 121 in the adapter 120 calculates the digital temperature signal detected by the temperature detection unit 113 based on several AD sampling values, and determines whether the digital temperature signal exceeds the preset temperature. If the digital temperature signal detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, then proceed to step twelve; if the digital temperature signals detected by the temperature detection unit 113 of the electrode 110 are all below the preset temperature, then continue to step eleven.

[0098] Step 12: When the first controller 121 in the adapter 120 detects that the temperature detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, it sends a corresponding signal through the first communication unit 126 so that the electric field generator 130 reduces or shuts down the corresponding alternating current signal until the temperature detected by the temperature detection unit 113 of the corresponding electrode 110 is below the preset temperature. The preset temperature can be in the range of 39℃ to 41℃, preferably 40.5℃.

[0099] It should be noted that the above process is described using the adapter 120 for quality monitoring of the electrode 110 as an example. Quality monitoring of the electrode 110 can also be performed by the electric field generator 130, or partially by the adapter 120 and the electric field generator 130 respectively. Details will not be elaborated here. Furthermore, the number of electrode 110s, the number of electrode units 112 in each electrode 110, and the setting of the sampling code are all exemplary descriptions and are not intended to limit this application.

[0100] Specifically, during the production process of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can send the test code array of the electrode sheet 110 to a host computer (not shown). The host computer (not shown) then compares the test code array with the standard code array to monitor whether each temperature detection unit 113 of the electrode sheet 110 is properly connected, thereby determining whether the electrode sheet 110 is qualified. This allows for the screening out of unqualified electrode sheets 110, ensuring that each temperature detection unit 113 of the manufactured electrode sheet 110 can be tested normally. The standard code array includes at least the first code from the first code and the second code. The specific process is as follows:

[0101] Step 1: Provide a qualified electrode sheet 110, connect the electrode sheet 110 to the aforementioned adapter 120, connect the aforementioned adapter 120 to the aforementioned electric field generator 130, connect the aforementioned electric field generator 130 to a host computer (not shown, such as a computer), and connect the host computer (not shown) to a display (not shown) so that the host computer (not shown) can control the display (not shown) to display the code array (i.e., standard code array) of the qualified electrode sheet 110 and the code array (i.e., test code array) of the tested electrode sheet 110' of the same batch and specifications as the qualified electrode sheet 110.

[0102] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection unit 113 of the qualified electrode sheet 110 for temperature detection. The aforementioned adapter 120 obtains a set of standard code array A according to the aforementioned encoding rules. This standard code array A is routed from the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown), and is finally stored in the host computer (not shown) as a standard code array for comparison.

[0103] Step 3: Provide a test electrode 110' of the same batch and specification as the qualified electrode 110, connect the test electrode 110' to the aforementioned adapter 120, the aforementioned adapter 120 obtains a set of test code array B according to the aforementioned coding rules, the test code array B is routed from the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown), and displayed on the display (not shown).

[0104] Step 4: The host computer (not shown) compares the test code array B with the standard code array A for consistency judgment. If the test code array B is consistent with the standard code array A, proceed to step 5; if the test code array B is inconsistent with the standard code array A, proceed to step 6.

[0105] Step 5: The display (not shown) shows that the test electrode 110' is "qualified", the test electrode 110' is placed in the good product area, and then steps 3 to 4 are repeated to test the next test electrode 110'.

[0106] Step Six: The display (not shown) shows that the tested electrode 110' is "unqualified". The tested electrode 110' is placed in the defective product area. Then, steps three and four are repeated to test the next tested electrode 110'.

[0107] In step six above, while the display (not shown) shows that the tested electrode 110' is "unqualified", the host computer (not shown) can also control the alarm (not shown) to sound an alarm, so as to warn the operator that the tested electrode 110' is "unqualified" and needs to be placed in the defective product area. The alarm (not shown) can be an audible alarm, a visual alarm, etc.

[0108] It should be noted that through the above quality inspection steps of the electrode 110, the standard code arrays of various qualified electrode 110s can be stored in the host computer (not shown) to form a standard code array library of qualified electrode 110s. When the same type of electrode sheet 110' is tested again, the corresponding standard code array A in the standard code array library can be called as the comparison code for the batch of electrode sheets 110' to be tested, and compared with the test code array B corresponding to the electrode sheet 110' to determine whether the batch of electrode sheets 110' is qualified.

[0109] The code combination of the standard code array A and the corresponding test code array B of the electrode sheet 110' in the above steps is composed of multiple bits of code, and is not limited to the 20-bit code combination corresponding to the electrode sheet 110 in the embodiment of Figure 2. It can be composed of 13-bit, 24-bit, etc. code arrangement combination.

[0110] The above steps are described with the adapter 120 performing quality testing of the electrode sheet 110 as an example. The quality testing of the electrode sheet 110 can also be performed by the electric field generator 130. Furthermore, the number of electrode plates 110 that the adapter 120 can connect to, the number of electrode units 112 in each electrode plate 110, and the setting of the sampling code are all exemplary descriptions and are not intended to limit this application.

[0111] It should be noted that in this embodiment, the control switch 124, which is electrically connected to the multiple grounding lines 118 of the electrode 110, and the bidirectional switching switch 125, which is electrically connected to the multiple dual-purpose signal lines 119 of the electrode 110, are both located in the adapter 120. However, in other embodiments, the control switch 124, which is electrically connected to the grounding lines 118, and the bidirectional switching switch 125, which is electrically connected to the dual-purpose signal lines 119, can also be located on the electrode 110 or in the electric field generator 130, which will not be described in detail here. In addition, the ADC unit 122 located in the adapter 120 can also be located in the electric field generator 130 and directly controlled by the second controller 131.

[0112] Figure 6 shows a schematic diagram of the tumor electric field therapy system 300 of the second embodiment of this application. Its electrode 310 also has a corresponding open space and free end. Unlike the tumor electric field therapy system 100 of the first embodiment shown in FIG1, in terms of spatial structure, the multiple electrode units 312 of the electrode sheet 310 of this embodiment are connected in a symmetrical connection manner. For example, the four electrode units 312 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column are connected by a column-direction connecting strip. At the same time, the four electrode units 312 located in the first row and fourth column, the second row and fourth column, the third row and fourth column, and the fourth row and fourth column are also connected by a column-direction connecting strip. As can be seen from the figure, the 10 electrode units 312 on the left and the 10 electrode units 312 on the right are symmetrically arranged.

[0113] It should be noted that for other related descriptions of the second embodiment, please refer to the related descriptions of the first embodiment, which will not be repeated here.

[0114] Second embodiment:

[0115] FIG7 is a schematic diagram of the tumor electric field therapy system 400 of the third embodiment of this application. Unlike the tumor electric field therapy system 100 of the first embodiment shown in Figure 1, the electrode sheet 410 of this embodiment has 13 electrode units 412, which are arranged in a spatial structure of five rows and five columns. Specifically, each of the first and fifth rows includes two electrode units 412, and the two electrode units 412 in each row are located in the second and fourth columns, respectively; each of the second to fourth rows includes three electrode units 412, and the three electrode units 412 in each row are located in the first, third, and fifth columns, respectively. Adjacent electrode units 412 in each of the five rows are connected by a connecting strip (unlabeled). Adjacent electrode units 412 in each of the first, third, and fifth columns are also connected by a connecting strip (unlabeled).(Unlabeled) Connections. The electrode unit 412 located in the first row and second column is connected to the electrode units 412 located in the second row and first column and the first row and third column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the first row and fourth column is connected to the electrode units 412 located in the second row and third column and the first row and fifth column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the fifth row and second column is connected to the electrode units 412 located in the fourth row and first column and the fourth row and third column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the fifth row and fourth column is connected to the electrode units 412 located in the fourth row and third column and the fourth row and fifth column respectively via a connecting strip (unlabeled). Figure 8 is a schematic diagram of the circuit connection between an electrode plate 410 and an adapter 420 of the tumor electric field therapy system 400 shown in Figure 7. As shown in Figure 8, the 13 electrode units 412 are configured in three rows and five columns in the circuit connection. The first two rows each contain 5 electrode units 412, and the third row contains 3 electrode units 412. Therefore, only three of the four control switches 424 are connected to three grounding wires 418, and the other control switch 424 is left floating. A wire (unlabeled) is shorted at a corresponding position in the same row. That is, a wire (unlabeled) is set at the intersection of the three rows and four columns in the circuit connection and shorted to the grounding terminal 413A of the temperature detection unit 413 in the same row, and at the same time shorted to the signal terminal 413B of the temperature detection unit 413 in the same column.

[0116] Referring again to Figure 8, under normal circumstances, when the electrode sheet 410 has 13 electrode units 412, and each electrode unit 412 corresponds to a temperature sensor 414 and a diode 415, that is, the corresponding detection positions numbered 1 to 13 of the electrode sheet 410 all have temperature sensors 414, and the codes are all 1. Combining the 20 codes, we obtain the 20-bit standard code array 11111 11111 11102 22222 corresponding to the electrode sheet 410 in this embodiment. When the temperature sensor 414 is open-circuited, assuming that the temperature sensor 414 at detection position number 1 is open-circuited, the obtained 20-bit test code array is 21111 11111 11102 22222. When the temperature sensor 414 short-circuits, assuming the temperature sensor 414 at detection bit 1 short-circuits, the resulting 20-bit test code array is 01111 11111 11111 11111.

[0117] Based on the above coding rules, the quality of the electrode sheet 410 can be detected during use, so that the electrode sheet 410 can be replaced in time to avoid low-temperature burns. For the specific process, please refer to the relevant description in the first embodiment, which will not be repeated here.

[0118] Figure 9 shows a schematic diagram of the circuit connection between the electrode sheet 510 and the adapter 520 in the fourth embodiment of this application. (See page 23 / 27 of the specification, 26 CN)The electrode plate 410 and adapter 420 of the third embodiment shown in Figure 8 differ in that the 13 electrode units 512 in this embodiment are configured in a four-row, four-column configuration in the circuit connection. The first three rows each contain four electrode units 512, and the fourth row contains one electrode unit 512. Therefore, only four of the five bidirectional switching switches 525 are connected to the dual-purpose signal line 519, and the other bidirectional switching switch 525 is left floating. A wire (unlabeled) is shorted at a corresponding position in the same row. That is, a wire (unlabeled) is set at the intersection of the four rows and two columns in the circuit connection and shorted to the ground terminal 513A of the temperature detection unit 513 in the same row, and at the same time shorted to the signal terminal 513B of the temperature detection unit 513 in the same column.

[0119] Referring again to Figure 9, under normal circumstances, when the electrode sheet 510 has 13 electrode units 512, and each electrode unit 512 corresponds to a temperature sensor 514 and a diode 515, that is, when the corresponding detection positions of the electrode sheet 510 numbered 1-4, 6-9, 11-14, and 16 all have temperature sensors 514, and the codes are all 1, the 20 codes are combined to obtain the 20-bit standard code array 11112 11112 11112 10222 corresponding to the electrode sheet 510 in this embodiment. When the temperature sensor 514 is open-circuited, assuming that the temperature sensor 514 at detection position number 1 is open-circuited, the obtained 20-bit test code array is 21112 11112 11112 10222. When the temperature sensor 514 short-circuits, assuming the temperature sensor 514 at detection bit 1 short-circuits, the resulting 20-bit test code array is 01112 11112 11112 10222.

[0120] Based on the above coding rules, the quality of the electrode sheet 510 can be detected during use so that the electrode sheet 510 can be replaced in time to avoid low-temperature burns. For the specific process, please refer to the relevant description in the first embodiment, which will not be repeated here.

In terms of spatial structure, the arrangement of its electrode units is the same as that of the tumor electric field therapy system 400 shown in Figure 7. The difference from the tumor electric field therapy system 400 shown in Figure 7 is that the setting method of the connecting strip is different in spatial structure to suit different application methods, such as horizontal or vertical application. Specifically, in the electrode pads 610 of the tumor electric field therapy system 600 shown in Figure 10, no connecting strip is provided between the electrode unit 612 located in the second column of the first row and the two electrode units 612 located in the fourth column of the first row and the first column of the second row; the electrode unit 612 located in the fifth row...No connecting strips are provided between the four columns of electrode units 612 and the two electrode units 612 located in the second column of the fifth row and the fifth column of the fourth row; no connecting strips are provided between the two electrode units 610 located in the fifth column of the second row and the fifth column of the third row; no connecting strips are provided between the two electrode units 610 located in the fifth column of the second row and the fifth column of the third row.

[0123] Third embodiments:

[0124] FIG12 shows a schematic diagram of a tumor electric field therapy system 800 according to the seventh embodiment of this application. Unlike the tumor electric field therapy system 100 shown in FIG1, the electrode sheet 810 of this embodiment has 9 electrode units 812, which are arranged in three rows and three columns in spatial structure. Figure 13 is a schematic diagram of the circuit connection between an electrode plate 810 and an adapter 820 of the tumor electric field therapy system 800 shown in Figure 12. As shown in Figure 13, the nine electrode units 812 are configured in two rows and five columns in the circuit connection. The first row contains five electrode units 812, and the second row contains four electrode units 812. Therefore, only two of the four control switches 824 are connected to the ground wire 818, and the other two control switches 824 are left floating. A wire (unlabeled) is shorted at a corresponding position in the same row and five columns. That is, a wire (unlabeled) is set at position A on page 24 / 27 of the instruction manual (CN 121371478 A) to short the ground terminal 813A of the temperature detection unit 813 in the same row and short the signal terminal 813B of the temperature detection unit 813 in the same column.

[0125] Continuing to refer to Figure 13, under normal circumstances, when the electrode plate 810 has 9 electrode units 812, and each electrode unit 812 corresponds to a temperature sensor 814 and a diode 815, that is, the corresponding detection positions of the electrode plate 810 numbered 1 to 9 all have temperature sensors 814, and the codes are all 1. Combining the 20 codes, we obtain the 20-bit standard code array 11111 11110 22222 22222 corresponding to the electrode plate 810 in this embodiment. However, when the temperature sensor 814 is open-circuited, assuming...If the temperature sensor 814 at detection position 1 is open-circuited, the resulting 20-bit test code array is 21111 11110 22222 22222. When the temperature sensor 814 is short-circuited, assuming the temperature sensor 814 at detection position 1 is short-circuited, the resulting 20-bit test code array is 01111 11110 22222 22222.

[0126] Based on the above coding rules, the quality of the electrode 810 can be detected during use, so that the electrode 810 can be replaced in time to avoid low-temperature burns. For details, please refer to the relevant description in the first embodiment; it will not be repeated here.

[0127] Figure 14 shows a schematic diagram of the circuit connection between the electrode 910 and the adapter 920 in the eighth embodiment of this application. Unlike the electrode plate 810 and adapter 820 of the seventh embodiment shown in Figure 13, the nine electrode units 912 in this embodiment are configured in three rows and three columns in terms of circuit connection, with each row containing three electrode units 912. Therefore, only three of the four control switches 924 are connected to the ground wire 918, and the other control switch 924 is left floating. Only three of the five bidirectional switching switches 925 are connected to the dual-purpose signal line 919, and the other two bidirectional switching switches 925 are left floating.

[0128] Continuing to refer to Figure 14, under normal circumstances, when the electrode sheet 910 has 9 electrode units 912, and each electrode unit 912 corresponds to a temperature sensor 914 and a diode 915, that is, the corresponding detection positions of electrode sheet 910 numbered 1-3, 6-8, and 11-13 all have temperature sensors 914, and the codes are all 1. Combining the 20 codes, we obtain the 20-bit standard code array 11122 11122 11122 22222 corresponding to the electrode sheet 910 in this embodiment. When the temperature sensor 914 is open-circuited, assuming that the temperature sensor 914 at detection position number 1 is open-circuited, the obtained 20-bit test code array is 21122 11122 11122 22222. When the temperature sensor 914 short-circuits, assuming the temperature sensor 914 at detection bit 1 short-circuits, the resulting 20-bit test code array is 01122 11122 11122 22222.

[0129] Based on the above encoding rules, the quality of the electrode sheet 910 can be detected during use, so that the electrode sheet 910 can be replaced in time to avoid low-temperature burns. For the specific process, please refer to the relevant description in the first embodiment, which will not be repeated here.

[0130] It should be noted that for other relevant descriptions of the third embodiment, please refer to the relevant descriptions of the first embodiment, which will not be repeated here.

[0131] The substrate of the electrode sheet of this application is electrically connected to the same electrode unit and through the same dual-purpose signal line.The corresponding temperature detection unit's signal terminal, while transmitting both alternating electrical signals and DC signals for temperature signal acquisition via a dual-purpose signal line, also significantly reduces the number of conductive traces (grounding wires, dual-purpose signal lines) laid on it, reducing the wiring difficulty of the substrate, simplifying the manufacturing process, reducing the weight of the substrate, and lowering manufacturing costs; at the same time, it can achieve real-time and comprehensive monitoring of the temperature of all electrode units on the electrode sheet without increasing the weight of the electrode sheet or the number of cores in the first cable electrically connected to the electrode sheet, thereby achieving quality inspection of the electrode sheet.

[0132] In the tumor electric field therapy system of this application, the same type of adapter can be adapted to various electrode sheets with different numbers of grounding wires and dual-purpose signal lines. Although the adapter may have a floating bidirectional switching switch and / or control switch for different electrode sheets, it improves its adaptability.

[0133] Referring to FIG15, this application also provides an electrode sheet quality detection method, which includes the following steps:

[0134] S110: Determine the temperature detection signal of each electrode unit in the electrode sheet. Specification 25 / 27 pages 28 CN 121371478 A

[0135] Specifically, referring to FIG2, the switching unit is controlled so that at least one column group in the corresponding electrode sheet 110 is connected to the corresponding temperature sampling point; the control switch 124 corresponding to each row group is controlled so as to sample the analog temperature signal of the corresponding electrode unit 112 based on the corresponding temperature sampling point, so as to determine the temperature detection signal of each electrode unit 112 in each electrode sheet 110.

[0136] S120: Determine the test code array of the electrode sheet according to the temperature detection signal.

[0137] Specifically, the temperature detection signal is characterized by a voltage value. The test code array for the electrode 110 is determined based on the temperature detection signal, including: determining the voltage range of the voltage value; determining the code corresponding to the temperature detection unit 113 based on the voltage range of the voltage value, wherein different voltage ranges correspond to different codes; and generating a test code array for the corresponding electrode 110 based on the code corresponding to each temperature detection unit 113. For example, the test code array includes at least one of a first code, a second code, and a third code, wherein the first code indicates that the temperature detection unit 113 is in a normal state, the second code indicates that the temperature detection unit 113 is in an open-circuit state or an unset state, and the third code indicates that the temperature detection unit 113 is in a short-circuit state.

[0138] S130: The test code array is compared with the standard code array to identify the fault condition of each temperature detection unit in the corresponding electrode, or to determine whether the corresponding electrode is qualified.

[0139] Specifically, during the use of electrode pad 110, the test code array can be compared with the standard code array to identify the fault status of each temperature detection unit 113 in the corresponding electrode pad 110, so as to realize the quality detection of electrode pad 110 during use. When a faulty temperature detection unit 113 in electrode pad 110 is identified, the tumor electric field quality system 100 is also controlled to issue a first reminder message, and the electric field generator 130 is controlled to continue to work.

[0140] After comparing the test code array with the standard code array, the number of faulty temperature detection units 113 in electrode pad 110 is also determined, and the electrode pad 110 is judged to need to be replaced based on the number of faulty temperature detection units 113 in electrode pad 110. When it is determined that the electrode pad 110 needs to be replaced, the tumor electric field therapy system 100 is controlled to issue a second reminder message, and the electric field generator 130 is controlled to stop working.

[0141] Specifically, during the production process of electrode sheet 110, the test code array and the standard code array can be compared for consistency to determine whether the corresponding electrode sheet 110 is qualified, thereby realizing the quality inspection of electrode sheet 110 during the production process. After determining whether the corresponding electrode sheet 110 is qualified, the test code array, the standard code array, and the judgment result of whether the electrode sheet 110 is qualified can also be displayed, and a corresponding reminder message can be issued when the electrode sheet 110 is unqualified.

[0142] Although the various operations are depicted in the accompanying drawings in a specific order, this should not be construed as requiring these operations to be performed in the specific order shown or in a sequential order, nor should it be construed as requiring all the operations shown to be performed to obtain the desired result.

The second memory (not shown) stores a computer program, which, when executed by the second controller 131 (or 331, etc.), implements the aforementioned electrode quality detection method.
